What was the main reason for Prophet of Islam’s accomplishment in conveying his message?

The Holy Prophet (s.w.a.) carried the message of knowledge, yet there was no knowledge in that society. He carried the message of justice, yet there was no trace of justice in that society and powerful people and bullying rulers dominated people's lives and possessions. He was the messenger of morality, leniency, forgiveness, justice, and kindness, yet that society was devoid of such characteristics in the real sense of the word. The society was full of unkind, bullying, immoral, ignorant, and prejudiced people who were unjustifiably arrogant and who had their hearts set on carnal desires.

It was in such tough and fanatic conditions and in such a dry desert that the Holy Prophet (s.w.a.) grew up. And this 13-year period finally ended in the establishment of the Prophet's rule. He formed a community on the basis of monotheism, knowledge, justice, morality, ethics, and generosity. He transformed humility into dignity and savagery into brotherhood. He turned fanaticism into tolerance and reasoning. He transformed a state of ignorance into knowledge. He built a strong and logical foundation on the basis of which Muslims could reach the peaks of global civilizations for centuries and could rise to new heights which were unprecedented in human history.

His rule did not last any more than ten years. You just see what proportion of a nation's lifespan could those 13 years and the following ten years constitute. It is like a moment which passes very quickly. During such a short time, a great movement was started which could well be said to have divided human history into two eras: the pre-Islamic era, and the post-Islamic era. The Holy Prophet (s.w.a.) pushed humanity forwards, strengthened the bases of morality, and left unforgettable lessons for all humans. You should consider the greatness of Mab'ath* from such a perspective.

There were, of course, a number of interrelated factors which led to this success. But this success was mainly due to the Prophet being full of spirituality, purity, loyalty, and relying completely on God. This was a major and decisive factor in his success. Prior to his prophethood, the Holy Prophet (s.w.a.) was the most knowledgeable and the wisest of the people of Mecca. He was the most generous, respectable, and decent person in the area where he lived.

Among those people, this prominent person enjoyed the blessing of God and the responsibility was put on his shoulders. This was because God had put him to the test before. God knew His servant and knew who He was assigning this responsibility to. The Holy Prophet (s.w.a.) stood firm. His resistance and his perseverance that was accompanied by a deep knowledge of the goal he was pursuing and of the path he was treading supported all the achievements of the Holy Prophet (s.w.a.) and led to the success of this great movement. One who is right always wins but there are some prerequisites. In order for the right to win, one must defend it. To help righteousness win, one must persevere on the path of righteousness.
